To all whom it may concern:

Be it known that I, .WERNER Konnn, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Printing Devices for Registering Cash and the like, (for which I have filed application in Germany, Oct. 22, 1919,) of which the following is a specification. I

This invention relates to printing devices for registering cash and the like, of the kind serving for making inked prints, and this in particular such as are adaptedto offer a great deal of safety against fraud by rendering it impossibleto subsequently alter the print. To this end-in accordance with this invention, the typesor ciphers of the printing device are provided, within their contours, with points having theform of center-punches and being adapted to pierce the material on which the print is to be made during the printing operation.

One embodiment of the essential elements of the subject matter of the invention is shown by way of example in the annexed drawing in which Figure 1 is a side view of a portion of ,a type-wheel,

Fig. 2 a top view thereof,

Fig. 3 atop view of a type on an enlarged scale, 1

Fig. 4 a corresponding side view thereof,

Fig. 5 a sectional view taken on line 5--5 in Fig. 3, along with the counter die belonging thereto,

Fig-6 a top view of a portion of the counter die and a Fig. 7 a reproduction of the print made by several of the types.

Referring to the drawing, thetype-wheel A is constructed inthe manner of a toothed wheel. On the top surface of each tooth a is there arranged a type, representing, say, a cipher. Each type comprises ridges a (see Figs. 3 to 5), forming the contours of the type, and is provided with points a having the form of center-punches and being lodged within said ridges a These points a are of such length as to project beyond the ridges. Further, these points a are disposed in rows a which lie in parallel to each other (Fig. 3). The counter die B (Figs. 5 and 6), destined for carrying the object to be printed, say a slip of paper or the like, is

provided for its part, with a series of grooves 79 disposed in parallel and running in the same direction as the rows a of points, the width of these grooves being somewhat largerthan the diameter of the cylindrical portion of the points a Ridges b confining the grooves b laterally serve as asupport for the slip of paper.

Before making a print the types, that is to say the ridgesa and the points a? are suitably inked. The print is made by the counter die Band therewith the sheet of paper being either moved toward the types, or else by moving the set of types toward the counter die. .During this printing operation, thepaper slip is pierced by the points a passing through the sheet into the grooves bflwhile thepaper around the perforations so formed is saturated with inlr. The result isthat there is no possibility whatsoever of subsequently tampering with the print by either closing up the perforations again or erasing theiprint. Besides this, the contours of the types belonging to one g1'ou say, for example, the types representing theciphers from O to 9 are so chosen types (seeFig. 7). Hence,-the print made by one type cannot be subsequently altered to resemble that of any other type by adding lines or perforations, and by these means again any forging of or-tampering with the prints is rendered practically impossible.

It may be noted that a printing device is already known in which the printing surface of-the types as also the counter die are provided with ribs and grooves in such a manner that when the counter die and the types come to be pressed together, the ribbed portion of the one member always comes to engage the grooved portion of the other member, and in which thepaper to be printed is cut by the edges of the ribbed member. However, by. this structure the legibility of the print is greatly impaired. 'Besides, the paper is very much weakened by the cuts running across the entire printing area of the types, and there consequently exists the danger of the print being injured by the paper tearing. All these drawbacks are entirely obviated by the subject matter of this invention.

In contradistinction to the perforations being made by a method of stamping, the

piercing of the paper or by other means of center-punch-shaped points embodies the advantage that it is no longer necessary to provide for the stamping element of each type an exactly shaped recess in the counter die or matrix, a

A device of this kind will not work properly whenever the stamping element and the matrix do not happen to accurately register, for which reason this prior form of construction is wholly unsuitable for printing deviceshaving an adjustable type arrangement, 2'. e. where the types are mounted on wheels, because in such an arrangement slight deviationsfrom the proper adjustment effected and caused, say, by lost motion of the adjusting gear mechanism, are practically unavoidable. In addition, this prior arrangement makes it imperative to provide for the different types correspondingly difierent matrices, since it is not possible to produce a single matrix which will at the same time correspond to a large number of different types. In contrast tothis prior construction, the arrangement of center-punch-shaped points in rows and the. possibility thereby created of simply grooving the counter die yields the advantage that the points will always encounter the grooves, which are given a suitable width for this purpose, regardless whether the type wheels have suffered a slight lateral displacement or not, or even when there happen to prevail differences of adjustment in their direction of rotation, so that the piercing of the object to be printed will be effected without difliculty.

In the place of a grooved counter die under certain circumstances a non-grooved block of rubber or a similar soft material may be used.
